Camponotus chilensis

This Chilean carpenter ant runs on a Mediterranean-type rhythm, easing off for a short seasonal slowdown rather than a deep winter, which gives the keeping year a gentle shape without the work of a hard hibernation. It grows into a large colony over time, so there is plenty of long-term progress to enjoy. Workers are nocturnal, so the nest comes alive in the evening and the foraging happens on a schedule that fits after-hours watching. The intermediate rating mostly reflects that light diapause it benefits from each year.

Sugars power the night-time foragers, so a permanent nectar feeder suits them well, while insect protein feeds the brood. A couple of protein meals a week keeps the queen laying steadily.

★★★ readily · ★★ moderately · ★ occasionally · ✗ not eaten

Begin the queen in a test tube and let her brood mature before moving to a ytong, plaster or hybrid nest around 50-70% on the damp side. Upgrade as the worker count climbs and the chamber fills, and recall that the short annual diapause means the colony quietens for a spell rather than needing constant expansion. Carpenter ants this size scale walls easily, so ring the arena with fluon, oil, or talc and water. ANTonTOP formicaria and starter kits match this genus through to a large colony.

This South American species likes a light seasonal cool, so plan for a short diapause once a year, then return it to normal warmth: no hard cooling is needed. Day to day, keep the nest at 22-26 °C and the arena at 20-28 °C, with nest humidity 50-70% and the arena at 40-60%. Warm just one end so the colony can choose its spot along the gradient.

The founding queen builds slowly, then the colony gathers pace once workers are established, eventually reaching several thousand. Eggs develop through to adult workers in roughly 6-10 weeks. You receive a laying queen together with her workers and brood.

• Central Chile has a Mediterranean-type climate, which is why this ant runs on a mild seasonal rhythm rather than a hard cold winter.
• The country’s geography, walled off by the Andes and the Atacama, has produced a distinctive and partly endemic insect fauna.
• Carpenter ants excavate wood to nest but do not consume it, and they defend the colony with formic acid and a bite.
• Foraging happens after dark, so the obvious size gap between slim minors and broad-headed majors is best seen under a dim light.

Is Camponotus chilensis good for beginners?

It is rated intermediate, mainly because it does best with a short annual cool rest, but it is otherwise straightforward.

Does Camponotus chilensis need a winter rest?

It takes a light diapause, a brief cool rest each year rather than a deep winter.

Does Camponotus chilensis sting or bite?

No, only a mild bite and no sting.

How big does the colony get?

A mature colony reaches several thousand workers.

How large is the queen?

The queen measures 14-16 mm.

How fast does it grow?

Eggs reach worker stage in roughly 6-10 weeks, slow at founding then faster.

What does it eat?

Sugar water or jelly and insects such as crickets and flies; seeds are not eaten.

Will it arrive alive?

Yes, a queen with workers and brood ships with a heat or cool pack, dispatched within 24 h with tracking.

Escape prevention. Coat the inner rim of every open arena with fluon (PTFE), or use talc-and-water or an oil barrier as a backup, and keep a tight, fine-mesh lid on top. Check the barrier regularly, since dust, condensation and feeding debris break a fluon line over time. Keep tubing connectors tight and seal any gaps in the nest.

Keeping reminders. Always offer fresh water and never let the nest dry out completely. Give carbohydrates continuously and protein a few times a week, and remove uneaten insect prey within 24 hours before it moulds. Keep the formicarium out of direct sunlight and away from constant vibration, which stresses a young colony. A water-filled test tube plugged with cotton makes an ideal spare incubator whenever you need one.

Before you buy – do not rehouse too early. Have a test-tube setup or a small formicarium with an outworld and a working barrier ready before your colony arrives. A founding colony grows slowly at first, which is normal. Moving a small colony into a large nest too soon invites mould, mites and stress, and the workers die off one by one. Keep the colony in its open test tube on the arena, plug the nest entrance with cotton, and open up the next chambers only once the colony fills roughly 10-15% of the space.

What we ship. Every colony ships with a live-arrival guarantee, backed by our 24h unboxing-video guarantee: if the queen does not arrive alive, we reship free. Parcels travel with DHL, InPost (PL) or EMS, with a heat or cold pack to suit the season, packed discreetly and securely. We ship across the EU and worldwide, with free shipping over the Europe threshold.
